I currently have 195/50/15's on civic vti-r rims, on my da9.

They should be 195/55/15's, and thats ideally what I would like to have on.

One of my rear tyres has an air bubble in it, and I'm reluctant to leave it on the car in case it blows out.

I'm thinking of replacing both rear tyres with new ones, in 55 profile, even though they both have very good tread left.

My question is, will having 50 profile on one end, and 55 profile on the other, cause me any huge problems? I am planning to do it for 5000-10000kms (the life of the existing 50 profile tyres)
